makaveli Posted May 5, 2006 Share Posted May 5, 2006 (edited) Ok this is going to sound very strange! this has happened twice, i have a desk lamp, (halogen tube one (daylight bulb)) and twice this has happened the lamp and Base unit are approx 100cm away from each other (around a yard) and these to occasions when i have powered on my lamp, the Computers Internal Speaker beeps, (much similar to your "startup beep"!) any ideas what on gods earth this is?? cause it sure as heck has baffled me! i did think interferance, but what could it be interfereing with its not a life or death hardware issue, infact i find it a bit amusing Edited May 5, 2006 by TCH-Tim Quote Link to comment Share on other sites More sharing options...
TCH-Andy Posted May 5, 2006 Share Posted May 5, 2006 Basically it is interference, yes. Because of the way that a tube type lamp works, you tend to get electrical noise at startup. It should clear as soon as it's runing at full power. Quote Link to comment Share on other sites More sharing options...
makaveli Posted May 5, 2006 Author Share Posted May 5, 2006 yeah its only when the tubes are flashing on, i just found it mad, simlpy cause my TV does get intererance, but that recieves wireless signals, my PC doesnt unless the bluetooth adapter is plugged in. the whole thing just made me wonder..

TCH-Tim Posted May 5, 2006 Share Posted May 5, 2006 I used to have a set of PC speakers that would start buzzing seconds before my cell phone started ringing. Just the way it is. Quote Link to comment Share on other sites More sharing options...
cajunman4life Posted May 5, 2006 Share Posted May 5, 2006 I used to have a set of PC speakers that would start buzzing seconds before my cell phone started ringing. Just the way it is. So if you got good enough, you could answer the phone before it rang? lol Quote Link to comment Share on other sites More sharing options...
abinidi Posted May 5, 2006 Share Posted May 5, 2006 I used to have a set of PC speakers that would start buzzing seconds before my cell phone started ringing. Just the way it is. I have that same trouble with my work computer So if you got good enough, you could answer the phone before it rang? lol Yes! You laugh, but I'm almost always holding my phone in hand before it actually rings.... Quote Link to comment Share on other sites More sharing options...
kfordham281 Posted May 5, 2006 Share Posted May 5, 2006 My Siemens S66 cell phone does this even when it doesn't ring. Middle of the night and I hear speaker interferance. Pretty annoying actually.... Quote Link to comment Share on other sites More sharing options...
makaveli Posted May 5, 2006 Author Share Posted May 5, 2006 i know what thats about, its the network sending updates and "where are you" singals. it happens a bit before calls as the network sends a signal the "where are you" bounces it back, then your phone rings sometimes you can asnwer the phone as soon sas "answer" comes on screen its great Quote Link to comment Share on other sites More sharing options...
stevevan Posted May 5, 2006 Share Posted May 5, 2006 Without going into a lot of the technical mumbo jumbo, Bruce and Andy are correct. With my job, we deal with various types of interference on a daily (sometimes hourly) basis. There are several different things you can do, but you just have to find the fix that's right for your particular situation. Quote Link to comment Share on other sites More sharing options...
Samrc Posted May 5, 2006 Share Posted May 5, 2006 We use high-powered radios at the manufacturing facility and if someone is wearing one on a belt while near my computer, my monitor buzzes and when they talk the screen turns into window blinds. My own radio is stored near my computer when plugged in. Once in a while I will have it turned on but not unplugged and a couple of the smarties like to BUZZ me when they know that I have not moved it yet.

makaveli Posted May 5, 2006 Author Share Posted May 5, 2006 i have "personal radios" and they do interfere with CRT screens but my LCD doesnt seem to budge with nay RF signals. got radios for when im out and about in the outdoors to keep in contact with groups of people if were cycling or doing other things you need radios for Quote Link to comment Share on other sites More sharing options...
Deverill Posted May 6, 2006 Share Posted May 6, 2006 "Back in the day" we used AM radios tuned to no particular station to see if our computers were hung up or just slow. If they were computing they would make chirps and beeps so we knew it was working. Quote Link to comment Share on other sites More sharing options...
Samrc Posted May 6, 2006 Share Posted May 6, 2006 Back in the day, if I used a radio too close to my Bernoulli box it was unhappy but it never occurred to me to use the radio for testing! Quote Link to comment Share on other sites More sharing options...
chatbug Posted May 6, 2006 Share Posted May 6, 2006 I think CRT monitors are affected by cell phone and other interference because it's dependent on magnetism, am I correct? Quote Link to comment Share on other sites More sharing options...
Kevan Posted May 6, 2006 Share Posted May 6, 2006 When my office was near the road I could sometimes hear the truckers radios on my PC speakers. RF interference all over the place... Quote Link to comment Share on other sites More sharing options...
makaveli Posted May 6, 2006 Author Share Posted May 6, 2006 I think CRT monitors are affected by cell phone and other interference because it's dependent on magnetism, am I correct? yeah.. you know why i know that.. i stuck a huge magnet on a screen for a laugh and wrecked it!

chatbug Posted May 6, 2006 Share Posted May 6, 2006 yeah.. you know why i know that.. i stuck a huge magnet on a screen for a laugh and wrecked it! Well, I know that CRT monitors uses magnets and/or electric fields to adjust the path of a stream of electrons, which hit a (phosphorus?) screen and cause it to illuminate. I think what you did is actually wreck the screen that the electrons shoot to... permanently warping its originally-flat structure. Don't try putting a magnet to your CRT monitor at home (unless you don't want it anymore)... even though your screen will look amusingly pretty for a while. What I wasn't sure is whether the signal generated by your cell/mobile phone or other RF interference-causing devices are actually affecting the magnetic field directly...

chatbug Posted May 7, 2006 Share Posted May 7, 2006 A friend of mine lived in another friend's house for a while... and everytime at night, the telephone starts dialing *all by itself* on speakerphone!!

makaveli Posted July 29, 2006 Author Share Posted July 29, 2006 sorry to drag this up again, but my pc is going mad again! there is a storm prdicted could this be making the pc go mad? Quote Link to comment Share on other sites More sharing options...
TCH-Andy Posted July 29, 2006 Share Posted July 29, 2006 That depends on what you mean by going mad.... Generally I'd have said no. Electrical storms can have an effect if they are very close, but usually the impact is seen as power surges etc down the electricity cables.

makaveli Posted July 29, 2006 Author Share Posted July 29, 2006 well the "beeps" started going (like the lamp caused) and the speakers were crackling like an old record. Quote Link to comment Share on other sites More sharing options...
TCH-Andy Posted July 29, 2006 Share Posted July 29, 2006 If you have unshielded speaker cables, then an electrical storm (even at a distance) could cause the crackling. With the beeps, that could also be caused, but only when the electrical storm is much closer. Quote Link to comment Share on other sites More sharing options...
stevevan Posted July 29, 2006 Share Posted July 29, 2006 Just out of curiousity, have you plugged your pc into a good surge supressor? There are also filters available for your audio too...it just depends upon how much you are willing to spend. Quote Link to comment Share on other sites More sharing options...
makaveli Posted July 29, 2006 Author Share Posted July 29, 2006 yep all my pc stuff is on a surge/spike protector its fine now it was just a little confusing at the time to me, as in the past my speakers have only been affected by radio waves from my Radio sets and Mobile phone Quote Link to comment Share on other sites More sharing options...
TCH-Andy Posted July 29, 2006 Share Posted July 29, 2006 It sounds as if you have some poor screening on some of the cables / connectors somewhere - hence you are getting the interference. Quote Link to comment Share on other sites More sharing options...
makaveli Posted July 29, 2006 Author Share Posted July 29, 2006 time to have a nosey round then and check things, i have to admit when it comes to my pc, when its running ill leave it, ill not check it often, its almost as silly as a pilot not doing his pre-flight walk around and check when i think of it Quote Link to comment Share on other sites More sharing options...
